I used the find nearby place name for lat 51.66611111 lon -0.807777 which should spot exactly on Bradenham but it returns Slough which is somewhat to the west. It is of note that I moved Bradenham recently. How long does it take for the database to catch-up. It shows correctly on the aerial (google) view.

The updates should normally be propagated to all servers instantaneously. We have moved some functionality to a new server and parts of it was not updated during this process for some days.
The findNearbyPlacename is now returning the most current data.
